THE LIGHTING SYSTEM INSTALLED ON BUS STOP USING SOLAR CELL

摘要

PURPOSE: A sunlight illuminating system is provided to save electric energy by turning on or off a light emitting device according to external illumination. CONSTITUTION: A solar panel(1) generates electricity using sunlight. A chargeable battery stores electricity produced by a solar panel. A charging controller supplies electricity produced by the solar panel to the chargeable battery. A light emitting device(7) lights a bus stop(2) using electricity stored in the chargeable battery. An illumination sensor is arranged at the bus stop. A first controller turns on or off the light emitting device according to the external illumination sensed by the illumination sensor.
